Raw
Use a raw record; cooking changes weight.
Braised, grilled or sauced
Match the cooking method and log added ingredients.

PHOTO LOGGING
How to log roasted pork loin more accurately
A food photo can suggest the ingredient, but it cannot always reveal exact weight, hidden oil or preparation details. These checks turn an image guess into a better estimate.
- 01
Match the exact reference state: Pork, fresh, loin, whole, separable lean and fat, cooked, roasted.
- 02
Use edible grams. Calories are scaled from the selected per-100-g record; named portion weights come from the same local USDA record, while explicitly labelled gram examples are calculated.
- 03
Log oil, sauce, sweetener, salt and recipe ingredients separately.
- 04
Use a separate record when preparation changes the food state.
